Overview
The Vaisala WSP150 Surge Protector is a compact transient overvoltage suppressor designed for outdoor use. It can be used with all Vaisala wind and weather instruments. The WSP150 offers three-stage protection against surge currents up to 10 kA entering through the power and signal cables.
Mechanics
The Vaisala WSP150 Surge Protector has four channels, two of which are dedicated to power lines and two for data lines. Each channel uses a three-stage protection scheme as follows: first, there are discharge tubes, then voltage-dependent resistors (VDR), and finally, transient zener diodes. Between each stage, there are either series inductors or resistors. Both differential and common mode protection is provided for each channel: across the wire pairs, against the operating voltage ground, and against the earth. The WSP150 also includes noise filtering against HF and RF interference.
Applications
Vaisala recommends using the WSP150 when wind and weather instruments are installed on top of high buildings or masts and in open grounds, that is, anywhere with an elevated risk of lightning. Also, use the WSP150 if the cable length exceeds 30m or if users have unshielded, open-wire lines.

Vaisala WXT520: Weather station designed with monitoring systems in mind
The world’s weather is full of surprises. That makes a quality weather station a valuable piece of technology for monitoring systems. Vaisala's WXT520 multiparameter weather station is built with monitoring systems in mind. It monitors six weather parameters in real time, so users have the numbers on an unexpected rain storm or turbulent wind event. It can be a means of understanding weather events that caused a flush of nitrogen into a river or low water levels in a lake. What’s more, with the help of a data logger and telemetry system, it can deliver that information to one’s desk so she can stay dry and keep an eye on the data during a storm. Three core components make up Vaisala’s WXT520 weather station.

Sustainable Fishing in Alaska: Protecting the Salmon Capital of the World through Research
In the far north, the Alaska Peninsula stretches away from the Last Frontier into the Pacific Ocean. A narrow strip of land dotted with freshwater lakes and intruded upon by ocean inlets–this unique region is intimately connected with the surrounding water. Nestled halfway down the peninsula's southern coast are the small villages of Chignik. The area has historically been home to the Aleut people and has been heavily reliant on fishing for centuries. Home to commercial and subsistence fishing today, Chignik continues to rely upon the salmon returns to the surrounding villages, which are supported by scientists working tirelessly to understand and steward these fish populations.

NexSens X3 Data Logger Review
Extreme environments meet extreme design with the NexSens X3 Data Logger . The new logger offers the latest in real-time monitoring technology with wireless communication, a large plug-and-play sensor library and ultra-low power consumption, all in a waterproof marine-grade housing. The X3 is built to handle harsh weather, floods, high winds and rough seas, and it stands alone; no additional protective housing needed. With an operating temperature that ranges from -40°C to 70°C, the logger can withstand arctic environments and extreme heat. A conformal coating on the internal circuit board isolates it from moisture and humidity.
